What does the 01 Black shade look like?

01 Black creates an intense, deep-black line.

Can it create both thin lines and bolder wings?

Yes. The tapered brush supports subtle definition and broader, more dramatic lines. Vary the pressure or add more strokes when you want a thicker line or cat-eye.

Is the eyeliner designed to resist smudging?

Yes. Once set, it is smudge-proof and long-wearing. Its quick-drying formula also helps limit transfer and smudging.

Do I need to let the liner dry after applying it?

Yes. Allow the line to dry for a few seconds to help reduce transfer.
